.To all whom it may cncem:- Be it known that I, GEORGE F. BRETTELL,

.a citizen of the United States, residing at Shawnee, in the county of Pottawatomie and State of Oklahoma, have invented certain new and useful Improvements in Grease Cups, of which the following is a specifica- ,.tion.-

:My invention relates to grease cups and particularly contemplates the provisionof a simple and inexpensive device of this character comprising a shell adapted to contain a lubricant and a follower worked in such shell to force the lubricant therefrom, in combination with improved means to control the movement of said follower.

'- My invention further and specifically resides in the following features of construc tion, arrangement and operation, as will be hereinafter described with reference to the accompanying drawings, forming a part of this specification,in which like numerals are used ,to designate like parts throughout the several figures, and in which 'Figpre 1,is an elevation of my improved oil cup s through and through a ortion of the crank to which it is attached, ig. 4 is a view partly in elevation and artly in section embodyin aslightly modi ed form of my improve invention, and Fig. 5 is a perspective view of the spring holder.

.Inthe practical embodiment of my inven' tion I provide a grease cup comprising a shell 1 adapted to contain the lubricant and provided with a threaded nip 1e 2 extending centrallyfrom the base thereo the said nipple being rovided with an opening extending centra y therethrough and through the base of the shell 1, and adapted to be alined with an opening A through the bearing portion of a crank or the like B, when said threaded nipple 2 has been screwed within an opening formed adjacent to said opening A. A shel -l is further formed with a nut 3 upon its circumferential face adjacent the base theres. of and with an elongated upper edge 4 1111381'-' nall threaded. adjacent the bore of said shel, for the 1 reception of the external threadedbody ortion of the screw follower 5, preferably ormed hollow in order to lighten the same and provided with aflange 6 extending from its outer edge and provided with a-plurality of flat sides to form a nut.

' In order to prevent accidental rotation of the plug or screw follower 5 I provide a spring holder comprising a circular body portion 7 having a central opening 8 therethrough adapted to be held between the nut 3 at the base of the shell 1 and the portion'of the bearing of the crank B surrounding its opening into which the threaded nipple 2 is screwed said spring holder beingprovided with a clip 9 ada ted to be bent u on a por tion of said cranli B if desired. 'Fhe spring holder is further provided with an elon ated spring tongue 10 bent upwardly therefrom, and to lie along the body portion of the shell 1, the nut 3 at the base thereof being provided with a cut out, portion to allow said spring tongue 10 to liein close contact with said shell 1.

The tongue 10 extends above the shell 1 and is adapted adjacent its free end to suc ces'sively engage the fiat surfaces of the nut 6 of'the lug or screw follower 5 as the same is rotate withiinthe shell 1 to force the lubricant therefrom, said tongue 10 thus acting as a lock against said flat faces of said nut 6 to revent accidental rotation of said screw folower 5. To prevent the sprin tongue 10 being permanently sprung away om the nut 6 b hard and continued use, I provide the 7 she 1 with a pair of cars 11 extending outwardly therefrom at the sides of said tongue and form a bolt or pin 12 extending between said ears over the outer face of said tongue 10, thereby securely holding the same above its point of bending from its circular body portion 7. i In the form of my invention shown'in Fig.

4 I provide a shell 13, adapted to contain a lubricant, formed integral with. the bearing ortion A of a crank B and provided with an mternally threaded thickened outer edge adapted for the reception-of an intema y and externally threaded plug orreducin nut 15'having a flange 16 between-which am? said outer edge 14 o circular body portion 17-,of a spring holder of substantially the same construction as the the'shell 13 is claihped the holder previously described 'and""'shown-in' gag'ed by a spring tongue from -18 is of substantially t e samefor nation as h being rovided with a nut. 19st its upperedge' the ,11Q"

the plate 17 and of substantially the same formation or of greatly reduced length as will be seen. In this form the holder, comprising the cars 11 and the bolt or in 12 extending from the shell 1, is dispense with, theoperation, however, being substantially the same in both forms illustrated and described.

Having thus fully described my invention, I claim:

A grease cup of the character described comprising a shell having a threaded nip le for engagement with a support and provided with a nut formed thereon adjacent its lower end, having a recess in one of its flat surfaces, a follower threaded to screw with said shell and comprising a hollow body portion provided on its outer end with an enlarged nut having its flat surfaces in alinement with the surface of said shell, a spring holder comprising a body portion clamped between said shell and its support, a spring retaining clip extending from said body portion and bent into engagement within a recess formed therefor, a spring locking tongue extending from said body portion at a diametrically opposite point to said clip, and bent to lie within said recess in said body nut and to engage the fiat surfaces of said follower nut with its free end, said shell having pierced ears extending therefrom at the sides of said tongue, and a pin extending between and secured through said ears to prevent displacement of said tongue, substantially as described.

In testimony whereof I afiix my signature
